What is one characteristic of saturated fats?

Saturated fats are primarily characterized by the presence of single bonds between all the carbon atoms in their fatty acid chains. This structure signifies that each carbon atom is 'saturated' with hydrogen atoms, which is why these fats tend to be solid at room temperature. In contrast, the other options describe characteristics that do not apply to saturated fats; for example, the mention of multiple double bonds refers to unsaturated fats, while liquid fats are typically associated with unsaturated varieties. Additionally, the claim regarding heart health is misleading as saturated fats are generally linked to an increase in cholesterol levels, which can negatively affect heart health.
